Heater Makes Me Want to Chop Nose Off

The heater (house or car) turns my nose into a living hell of itchiness and congestion. It is so bad that it wakes me up. I turn off the heat and get some cool air in my body's air system and I go back to normal.

the amount of moisture a parcel of air can hold is dependant on temp.. warm air can hold more moisture. when air is cooled to its dewpoint and can not longer retain its moisture, it becomes saturated and must precipitate out. hence why a few warm winter days followed by a sudden temp drop brings snow or rain,, Likewise when a cold surface (beer can right out of the freezer) is introduced to a warmer temp, the air immediately around the can in cooled to the dewpoint , causing condensation or frost

on the flipside, if you take COLD air that already has low humidity, and heat it,, it's the opposite.. the relative humidity drops to almost nil...

come to chicago in january if if you ever want to experience the feeling of your snots freezing inside your nose

The little trick I learned when I lived in Flagstaff is to put a little vaseline in each nostril with a qtip. Seriously. Not much, and not far, but it makes a world of difference for congestion in the cold.
